| Popis: | Raman spectroscopy is used to study the molecular relaxation processes in the following alkaline earth metal nitrates: Ca(NO3)2, Sr(NO3)2, and Ba(NO3)2. The first-order crystal–melt phase transition in calcium, strontium and barium nitrates is found to be extended. A premelting region is revealed in these alkaline earth metal nitrates. Premelting phenomena are shown to manifest themselves in the temperature dependences of spectral parameters. |
